As shown in FIG. 3, mat bases 14-16
Is formed of a hard synthetic resin material (hard material) such as foamed polyethylene which can hold air bags 31 to 38 described later on the upper surface. It is made of a soft synthetic resin material (elastic material) such as elastic urethane foam which can be laid down.

The mat body 10 includes upper layers 17 to
19 is an air bag 31 to 31 together with the sides of the mat bases 14 to 16.
38 is formed in a two-layer structure covering the upper surfaces of the mat bases 14 to 16 from above.

The upper surfaces of the mat bases 14 to 16 are formed in a wavy shape, and the upper surface of the mat base 14 and the upper layer 1 are formed.
7, a gap 22 between the upper surface of the mat base 15 and the lower surface of the upper layer 18, and a gap between the upper surface of the mat base 16 and the lower surface of the upper layer 19. 23
Are formed respectively.

The gap 21 has three strip-shaped air bladders 31 to 33, and the gap 22 has four strip-shaped air bladders 3 to 33.
4 to 37, one gap-shaped air bag 38 is provided in the gap 23.
Are arranged at the positions corresponding to the valleys of the waveform.

The air bladders 31 to 38 are inflated by the supply of air from a supply / discharge device 40, which will be described later, so that the lower portions of the air bladders 31 to 38 enter the valleys and are fixed. The upper portions of the upper layers to 38 project the portions corresponding to the air bags 31 to 38 of the upper layer sections 17 to 19 upward.

Therefore, a protrusion is formed on the outer surface of the mat body 10 due to the inflation of the air bladders 31 to 38 built in the mat body 10, and the protrusion lays on the mat body 10 due to the protrusion. The pressed state against the user's body and the non-pressed state when the air bladders 31 to 38 are contracted are alternately repeated, so that the user's body can be massaged.
